TIG type arc welding machine adopts advanced Pulse Width Modulation (PWM) technology and insulated gate bipolar transistor (IGBT) power module to convert power frequency to intermediate frequency, thereby replacing the bulky labor in traditional arc welding machine with a compact intermediate frequency transformer The high frequency (low frequency) transformer makes the machine have the advantag🏅es of small size, light weight, low noise, low power consumption and easy portability.

1. The whole machinﷺe and all parts are designed with three-proof, high reli🐷ability;

2. The power d🍬evices are all selected from well-known brands, and the core device IGBT is selected from Infineon, Germany;

3. The digital control system based on 32-bit ARM processor can reliably, flexibly and accurately adjust the air supply time, arc starting current, ramp-up time, peak current, base current, pulse frequency, duty cycle, cl⛄eaning effect, AC frequency, slow down time, crater current, post air supply time, etc.;

4. In AC mode, rectangular wave, triangular wave and sine wave can be sel൲ected for different welding 𓃲requirements;

5. Special arc starting design ensures 100% cold gun arc starting und💯er AC state;

6. The cleaning effeꦜct is flexible and adjustable to ensure that the welding seam is bright and beautiful;

7. High-speed DC pulse waveform output, the highest frequency can r✱each 200Hz, the arc is more rigid, the heat-affected zone is smaller, and it is more suitable for thin plate welding;

8. With overvoltage, undervoltage and phase loss protection, it can effectivelyꦉ prote๊ct the welding machine from the harsh power supply environment;

9. Applicable to generators and any grid voltage b✤etween three-phasꦆe 320V to 520V;

10. Equipped with water cooling interface, 💙optional water cooling components.
